## Description

If you're a student.. Are you struggling with the following math problems?

÷ Division: Don't know how to do a long division

If you're a math teacher or parents...

"Math: Unknown" is a step-by-step math calculation game which will teach players "how" to calculate in the correct order.

Unknowns are numbers you have to solve.

The more you solve unknowns, the more you know.

You will focus on 4 kinds of math operations i.e. addition, subtraction, multiplication and long division. It's like having your personal math tutor with you anywhere.. anytime.

The game has 4 main arithmetic operations. Each operation has 2 sets (A and B) and each set contains 8 levels of difficulty with unlimited number of problems. So you can play as many as you want, there is no limitation. The score (stars) you got will be accumulated for each set.

=== HIGHLIGHTS ===
[-] Subtraction with borrowing
[×] Detailed Multiplication
[÷] Long Division

=== DETAILS ===
For all questions, if you did it wrong, there will be corrections to show the correct answers

+ Gradually increases difficulty -- more number of digits
+ Automatically show carrying (regrouping) when necessary just to let you see how it is done on the paper.
+ Once you're familiar with carrying, you'll have to do it all yourself in higher levels.

[2] Subtraction:
- Starting with basic subtraction without borrowing
- Borrowing is needed in higher levels
- Borrowing is visualized by a single button press at the right time
- Visualized 2 ways of borrowing from the next place
-- Next place is a number with value more than 0
-- Next place is zero
- You'll learn when and how to borrow since the button will be active only at the right time
- Borrowing won't be shown in the later levels when you're familiar with it in order to let you do it all yourself

[3] Multiplication:
× Starting with basic
× More number of digits as level progresses
× Show carrying in early levels
× You don't have to do it all yourself, only a single row is needed to answer
× Relevant multiplication table is shown when necessary

[4] Division:
÷ Detailed Long Division
÷ Relevant multiplication table is shown so that you can quickly refer to it in division
÷ If you pick a correct quotient, the product (multiplication between divisor and a digit of quotient) will be shown automatically. What you have to do is see the table and pick the right one
÷ You will have to subtract and pull a digit from dividend yourself
÷ You will have to calculate from top to the remainder
÷ There won't be any multiplication table in higher levels so that you can practice the real problem which you have to guess what will fit

[5] Calculation Guides:
+ Animated steps of solving all types of calculations
+ Multiplication table of number 2 to 19
